Hi everyone. My name is Nic. I'm 64 and a nurse in the NHS but a complete novice in this health field (I work in mental health).

I don't have a diagnosis (yet) although I will be contacting my GP surgery on Monday for a blood test.

My question is: can different BG machines give "false" or inaccurate readings?

The backstory is for the past year or so I've been feeling tired during the day, sometimes I have to go out to the car park at work during break times and have a nap in the car.

No other symptoms: no excessive thirst, no getting up at night (although I make up for it by needing to use the loo 6-7-8 times in the mornings and regulate my fluids so I drink less in the afternoons/evenings). My diet's not good and I eat too much (although I have lost about 12lb in weight in the past 6-8 months).

The tiredness is what made my wife worried, so I bought a BG machine (something called a Kinetik) and, once I was in from work, spent the best part of an hour last night learning how to use it. When I finally did, my first "score" was 7.1 mmol/L.

This was after not eating since yesterday morning and drinking water only (work pressures!), so theoretically a "fasting" test. I looked up what that might mean, so to be sure I did it again about 30 minutes later, still without having eaten. This time the machine came up with 7.9mmol/L.

I told my wife and this morning she asked a friend of ours who was recently diagnosed as having Type 2 to come round. I then used her BG machine (sorry, don't know the make) and the score this time was 6.4mmol/L. I'd only had a coffee at this point.

This confusing me. Needless to say, I know the final word is in the hands of the GP after a blood test has been taken, but I'd welcome any initial insights from anyone who has experienced anything similar.

Thank you for reading this.
 
Hi and welcome!

Firstly all blood glucose meters have a margin of error of +\- 15% so the first two readings you describe are in line with that. You would likely find that different meters tend to read slightly lower or slightly higher overall, but they should operate within the margin for error and the general trends would likely be the same.

Regarding the reading of 6.4, random one-off readings don’t tell you too much as they are just that, a snapshot in time.

Having said all of that, none of those readings are ‘scary’ or particularly high.

There can be many reasons for fatigue and if the weight loss you mention wasn’t deliberate/planned, I’d expect the GP to investigate that too.

Do let us know how you get on!
